There are quite a few "remote SMS" apps on the Market, but none quite like ClockworkMod's DesktopSMS. Instead of the usually browser plugin, or dedicated web interface front end, DesktopSMS takes a versatile and familiar approach: Gmail. The app will intercept your incoming SMS messages and forward them to either Gmail, Gtalk, or both, so you can reply from your computer or tablet. Once the sent message hits the receiving end, it looks as if it came directly from your phone, so there's no confusion.

There's already an app that does the gTalk / JABBER IM sms type thing called gTalkSMS. It also lets you view contacts, call people, delete messages and read message streams and is always updated. https://market.android.com/details?id=com.googlecode.gtalksms
Although it's not from the clockworkmod guys...
